Hello @zubedude, and welcome to Mayo Clinic Connect.
I'm glad you found this online support group and posted your question. The thing about Connect is we cannot give medical advise, only our opinions. And those can be right or wrong because each person is unique and special and so are their circumstances.
For instance, I had a pounding and fast heart beat (120s) in the middle of the night many times. So bad at times it would literally shake the bed. It definitely caused anxiety. However, my symptoms were all due to Hypertrophic Cardiomyopathy, and since my septal myectomy I no longer suffer from this.
The reason I share this with you is to encourage you to mention this to your FP doctor or if you have a cardiologist mention these incidents to them. We can offer our opinions here, but we cannot diagnosis or recommend treatments. We can share our story, but still...we can only guess what is causing your issues at night. Do you have a trusted family doctor or cardiologist you can see?
